Improved vertical windlass



. UNITED STATES PATENT OFFICE@Y CHARLES PERLEY, OF NEW YORK', N. Y.

IMPROVED VERTICAL WINDLASS.

Specication forming part of Letters Patent No. 53,] 7S, dated March 13,1866.

To all whom it may concern.-

Be it known that I, CHARLES PERLEY, of the city and State of New York,have invented, made, and applied to use a certain new and usefulImprovement in Vertical Windlasses; and I do hereby declare thefollowing to be a full, clear, and exact description of the saidinvent-ion, reference being had to the annexed drawings, making partofthis specification, wherein- Figure l is a side view of my improvedwindlass, and Fig. 2 is a plan ofthe same.

Similar letters denote the same parts.

In Letters Patent granted to me May, 1863, a triangular capstan orvertical windlass is represented, the capstan f and chain-wheelsp poccupying a triangular position. In this patent an arrangement of wheelsis shown for communicatin gto the chain-wheelspp a slower movement thanto the capstan f, hence increasing the power of said chain-wheels p.

My present invention is an improvement upon that set forth in theaforesaid Letters Patent, and the same letters refer to like parts;hence it is unnecessary in this specication to go into the details ofconstruction and operation of the respective parts or to show all thegearing and operative parts. y

In the Letters Patent aforesaid both chain- Wheels p p are given aslower motion than the capstanf. It is found, however, that in vesselsengaged especially in inland navigation and coasting trade it isimportant to have two heavy chains and anchors for use in storms and onelighter chain and anchor for temporary use or for calm weather, and thatthe aforesaid chain-wheels p p move too slowly for rapidly drawing upthe light anchor.

The nature of my said invention consists in a chain-wheel upon thecapstan-shaft capable of being connected with the same, in combinationwith a power capstan or windlass driven by gearing that connects thesaid capstan-shaft with the said power windlass or chain-wheel, wherebythe apparatus has facility for operating upon a heavy chain with a slowmotion or upon a lighter chain with a faster motion, thus adapting thisapparatus'to vessels engaged in coasting or inland trade.

In the drawings, a is the triangular base of the capstan; b, the topplate of the same 5 p p, the chain-wheels, q g, the power-capstan and fis the capstan, with sockets h for the handspikes. These parts are to besubstantially the same as in aforesaid patent, the shaft z' of thecapstan f being connected, by suitable gearing in the base a, with theshafts of the chainwheelsp and capstans q. Around' the shaftz' of thecapstan f isachain-wheehp, adapted to a smaller chain than the wheelspp,and this chain-wheel p may be connected to the shaft z' by means of akey or pin introduced through a wheel or disk,g, upon the square shafti, entering a hole or recess in said chain-wheel p', or any othersuitable device may be provided for connecting the chain-wheel p withthe shaft t or disconnecting it therefrom, so that the capstan f can beworked while the chain-wheel p is stationary, or the chain-wheel pallowed to revolve as the chain is run out without rotating the saidcapstan f. This chain-wheel p may be sustained upon balls, if desired,to avoid friction, and the chains to the respective chain-wheels may beled in the direction indicated by the red lines.

It will be evident that if more than three chains are employed there maybe au increased number of chain-wheels placed either one above the otheron the shaft i and on the shafts of` the wheels p, or the base a may beadapted to the reception of three or more chain-wheels p andpower-capstans g. The capstan f may be sufliciently high to be operatedupon the deck above or it may be placed upon the chainwheel p.

What I claim, ters Patent, is-

lhe chain-wheel 10', in combination with the capstan f and chain-wheelp, substantially as set forth.

In witness whereof I have hereunto set my signature this 31st day ofJanuary,A.D.l866.

CHARLES PERLEY.

and desire to secure by Let- Witnesses LEMUEL W. SERRELL, GEO. D.WALKER.
